Clé TNT ESSENTIELB Hybride MOBILI-TV

Hi
On vacation in France I bought a Clé TNT ESSENTIELB Hybride MOBILI-TV. It worked perfect at several locations in France (Chambre, Montpellier, Contrexeville) and in Germany (Munster, Hamburg). However back in Norway there seem to be a problem using the Digital tuner, Analogue works fine.
I have tried to find the producer "Essentiel B" or to find a site where drivers can be downloaded. I have had no luck so far! Does anyone know the website of "Essentiel B" or a website for "Essential B" drivers and hardware support?
